Free Pole Barn Plans

Julian 2 FavoriteLoadingAdd to favorites List YOUR FAVORITES GapDice RANDOM PLAN

This step by step diy woodworking project is about free pole barn plans. The 16×20 pole barn has a gable roof. The project features instructions for building a simple and fairly cheap barn using common materials and tools. You need to set the posts into the ground and to secure them together to the top. In addition, attach a roof to protect the construction from bad weather. Make sure you take a look over the rest of plans to see alternatives and more projects for your garden.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a 16×20 pole barn

Building the posts

Building the posts

The first step of the project is to build the posts for the barn shed. The green posts are for the front of the barn. The brown posts are the ones for the corners of the barn. The yellow posts are the side posts. The blue posts are for the back of the barn (you can also use yellow posts for the back of the barn, if you want to simplify everything).

You need to set the posts into concrete for about 3-5′. Dig holes into the ground and remove the vegetation layer before inserting the screws. Use a post hole digger to get the job done quickly.

Fitting the poles

Fitting the poles

Use the color code from the diagram to place the posts properly. Use batter boards and string to lay out the posts in a professional manner. Apply the 3-4-5 rule to the corners to make sure they are square. In addition, make sure the diagonals are equal.

Fitting the back poles

Fitting the back poles

It is essential to take accurate measurements before fitting the posts.

Installing the posts

Installing the posts

Use a spirit level to plumb the posts. Tamp the bottom of the holes thoroughly and make sure it is plane. In addition, use temporary braces to lock the posts into place tightly while pouring the concrete in the holes. Let the concrete to dry out before continuing the project. Make sure the top of the side posts are horizontal and cut out any excess.

Fitting the supports to the sides

Fitting the supports to the sides

Fit the 2×4 supports to the sides of the barn, as shown in the diagram. Place the supports equally-spaced and lock them to the the poles using 2 1/2″ screws. Fit a 2×10 beam to the bottom, to add strength to the structure. Make sure you invest in weather-resistant lumber as the components will be exposed to moisture.

As you can notice in the plans, you need to make sure the supports overhang on both sides for 1 1/2″ screws.

Fitting the supports to the back

Fitting the supports to the back

Fit the 2×4 horiozntal supports to the back of the barn. In addition, fit the bottom beam to the posts. Drill pilot holes through the beams and insert 2 1/2″ screws into the posts.

Fitting the supports to the front

Fitting the supports to the front

Install the supports to the front face of the barn. You should remember that you can adjust the width of the opening to suit your needs.

Fitting the panels to the front

Fitting the panels to the front

Continue the project by attaching the T1-11 siding to the exterior of the barn. Align the sheets to the top supports and secure them into place using 1 5/8″ screws or nails. Leave no gaps between the components and secure them to the supports every 8″.

Fitting the panels to the back

Fitting the panels to the back

Fit the 4×8 sheets to the back of the barn. Align the edges and leave no gaps between the siding sheets.

Fitting the panels to the sides

Fitting the panels to the sides

Continue the project by fitting the panels to the sides of the barn. Make sure you leave no gaps and secure the sheets tightly to the horizontal supports.

Building the trusses

Building the trusses

Building the roof for the barn requires 2×6 lumber. Cut both ends of the bottom rafters at 30 degrees. Cut one end of the regular rafters at 60 degrees.

Fitting the supports

Fitting the supports

Next, you need to install the supports to the trusses. Cut the top of the supports at 60 degrees. Cut both sides of the middle support at 60 degrees.

Building the gussets

Building the gussets

Use 1/2″ plywood to make the gussets for the trusses. Mark the cut lines on the plywood sheet and get the job done with a circular saw.

Fitting the gussets

Fitting the gussets

Fit the gussets to the joints of the components, as shown in the diagram. Align the edges with attention and insert 1 5/8″ screws into the rafters.

Attaching the trusses

Attaching the trusses

Place the trusses to the top plates of the 16×20 pole barn. Place the trusses every 24″ on center. Use appropriate hardware to secure the trusses to the top supports of the barn. Use a spirit level to make sure the trusses are plumb.

Fitting the end gable panels

Fitting the end gable panels

Cut the panels for the gable ends at the right shape and attach them to the front and back of the pole barn, as shown in the diagram. Align the edges with attention and secure the panels to the supports using 1 5/8″, every 8″.

Building the overhangs

Building the overhangs

Build the front and the back overhangs for the barn shed. You can adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings.

Fitting the overhangs

Fitting the overhangs

Attach the overhangs to the front and to the back of the barn shed. Use 2 1/2″ screws to secure the overhangs to the structure, after drilling pilot holes.

Fitting the roofing sheets

Fitting the roofing sheets

Next, you need to attach the roofing sheets to the rafters, as shown in the diagram. Use 3/4″ tongue and groove plywood. Align the edges with attention and follow the pattern described in the plans. Secure the sheets to the rafters every 8″ with 1 5/8″ screws.

Fitting the overhang roofing

Fitting the overhang roofing

Cut the remaining pieces of plywood for the overhangs. Align the sheets and secure them to the rafters using 1 1/4″ screws. Leave no gaps between the components for a professional result.

Fitting the asphalt shingles

Fitting the asphalt shingles

Cover the roof with tar paper, making sure the strips overlap at least 2″. Then install the asphalt shingles starting with the bottom of the roof. Read here more about how to install the asphalt shingles.

Last but not least, you should take care of the finishing touches, as to be able to continue the process with the rest of the steps. Therefore, we recommend you to check if all the components are installed properly into place.

    This plan is missing the steps on how to close up gap for side overhangs between the end of the trusses and the siding to keep enclosed entirely

    • Julian at -

      If you want to seal those gaps you can fit blockings between the trusses and then install soffit.
